Component Diagram & Deployment Diagrams

INTRODUCTION ABOUT LAB

There are 66 systems (Compaq Presario) installed in this Lab. Their configurations are as follows:

Processor : AMD Athelon ™ 1.67 GHz

RAM : 256 MB

Hard Disk : 40 GB

Mouse : Optical Mouse

Network Interface card : Present

Software

All systems are configured in DUAL BOOT mode i.e., Students can boot from Windows XP or Linux as per their lab requirement.

This is very useful for students because they are familiar with different Operating Systems so that they can execute their programs in different programming environments.

Each student has a separate login for database access

Oracle 9i client version is installed in all systems. On the server, account for each student has been created.

This is very useful because students can save their work ( scenarios’, pl/sql programs, data related projects ,etc) in their own accounts. Each student work is safe and secure from other students.


Latest Technologies like DOT NET and J2EE are installed in some systems. Before submitting their final project, they can start doing mini project from 2nd year onwards.

MASM ( Macro Assembler ) is installed in all the systems

Students can execute their assembly language programs using MASM. MASM is very useful students because when they execute their programs they can see contents of Processor Registers and how each instruction is being executed in the CPU.

Rational Rose Software is installed in some systems

Using this software, students can depict UML diagrams of their projects.

Softwares installed: C, C++, JDK1.5, MASM, OFFICE-XP, J2EE and DOT NET, Rational Rose.

Systems are provided for students in the 1:1 ratio.

Systems are assigned numbers and same system is allotted for students when they do the lab.


Guidelines to Students

1. Learn what the UML is, what it is not and why it is relevant to the process of developing software-intensive systems

2. Master the vocabulary rules and idioms of the UML and in general how to speak the language efficiently

3. Under stand how to apply UML to solve a number of common problems

The user guide provides a reference to the use of specific UML features, However it is not intended to be a comprehensive reference manual for UML. That is focus on other book, The Unified Modeling Language Reference Manual

For the developer approaching the UML for the first time, the user guide is best-read linearly. All chapters are constructed so that each builds upon the contents of previous one, thus lending it as linear progression.

Description about UML

1. Model A model is a simplification of reality.

A model provides the blueprints of a system.

A model may be structural, emphasizing the organization of the system, or it may be behavioral, emphasizing the dynamics of the system.

We build models so that we can better understand the system we are developing.

We build models of complex systems because we cannot comprehend such a system in its entirety.

Through modeling, we achieve four aims.

Models help us to visualize a system as it is or as we want it to be. Models permit us to specify the structure or behavior of a system.

Models give us a template that guides us in constructing as system.

Models document the decisions we have made

2. Principles of Modeling

The choice of what models to create has a profound influence on how a problem is attacked and how a solution is shaped

Every model may be expressed at different levels of precision

The best models are connected to reality

No single model is sufficient. Every nontrivial system is best approached through a small set of nearly independent models

3. Unified Modeling Language (UML)

The UML is a language for

Visualizing Specifying

Constructing

Documenting


The UML is a Language

A modeling language is a language whose vocabulary and rules focus on the conceptual and physical representation of a system

The UML is a Language for Visualizing

Some programmers think of an implementation and then code it. Some programmers think mentally i.e. they even sketch out a few ideas on a paper. That means some things are best modeled textually, others are best modeled graphically. The UML is such a graphical language.

The UML is a Language for Specifying

Specifying means building models. It specifies of all the important analysis, design, and implementation decisions that must be made in developing a software project.

The UML is a Language for constructing

The UML is not a visual programming language, but its models can be directly connected to a variety of a programming language. This means that it is possible to map from a model in the UML to a programming language such as Java, C++.

The UML is a Language for Documenting

A Healthy software organization produces all sorts of artifacts in addition to raw executable code. These artifacts include

1. Requirements

2. Architecture

3. Design


4. Source code

5. Project plans

6. Tests

7. Releases

The UML addresses the documentation of a system’s architecture and all of its detail

4. Architectural views of UML

The user model view

- Use Case Diagram - The functionality of a system

The structural model view

- Class Diagram - The static structure of a system

- Object Diagram - The static structure of a system at a particular time

The behavioral model view

- Sequence Diagram - Interaction among elements of a system in a time sequence

- Collaboration diagram - Interaction among elements and their relations organized in time and space

- State Diagram - The status condition and responses of the elements of a system

- Activity Diagram - The activities of the system

The implementation model view

- Component Diagram - The organization of the elements realizing the system

The Environment model view

- Deployment diagram - Configuration of environment elements and the mapping of elements realizing the system into them

Viva Questions & Answers

1. What is a Class?

Ans. A class is a description of set of objects that share the same attributes, operations, relations and semantics.

2. What is a simple name?

Ans. Every class must have a name that distinguishes it from other classes. A name alone is known as a simple name

3. What is a Path name?

Ans. A path name is the class name prefixed by the name of the package in which that class lives

4. What is Attribute?

Ans. An attribute is a named property of a class that describes a range of values that instances of the property may hold

5. What is an Operation?

Ans. An operation is the implementation of a service that can be requested from any object of the class to affect behavior

6. What is responsibility?

Ans. A responsibility is a contract or an obligation of a class

7. What is a relationship?

Ans. A relationship is a connection among things

8. What is Dependency?

Ans. Change in one thing depends upon the another thing

9. How the dependency is rendered?

Ans. Dependency is rendered as a dashed directed line, directed to the thing being depended on

10. What kind of relationship for Generalization?


Ans. Generalization called an “is-a-kind-of” relationship

11. A class may have how many parents?

Ans. A class may have zero, one, or more parents

12. What is root or base class?

Ans. A class that has no parents and one or more children is called a root class or base class

13. What is a Leaf class?

Ans: A class that has no children is called a leaf class

14. What is the Generalization?

Ans: It means that objects of the child may be used anywhere the parent may appear, but not the reverse

15. How generalization is rendered?

Ans: It is rendered as a solid directed line with a large open arrowhead, pointing to the parent

16. What is Association?

Ans: An Association is a structural relationship that specifies that objects of one thing are connected to objects of another

17. How Association is rendered?

Ans: An association is rendered as a solid line connecting the same or different classes

29. What is stereotype?

Ans. It is an extension of the vocabulary of the UML

30. How stereotype is rendered?

Ans. It is rendered as a name enclosed by guillements and placed above the name of another element.
